Man found incompetent to stand trial for stabbing death of pregnant girlfriend

A Spokane Valley man suspected of stabbing his pregnant girlfriend to death won't stand trial for murder.

On Tuesday, a superior court judge dropped the charge against Robbie Bishop after deciding he wasn't mentally competent.

In a jailhouse interview Bishop, 22, admitted to the crime, and prosecutors had hoped to play the interview for the jury at trial, but the case never got that far, bogging down in mental health reviews and the deaths of several witnesses.

"I went to the kitchen and that's when she came at me again and that's when I took her to the ground and that's when I stabbed her," Bishop told KXLY4 Reporter Jeff Humphrey.

Bishop said he was acting in self defense when he stabbed his pregnant girlfriend back in 2009. He said he was fighting with Robin Anderson over who would get custody over their son when the baby was born.

"He's trying to push it off as self defense? I mean maybe one or two stabs but over 70? And the majority of them were the baby," Anderson's friend Lynn Doidge said.

Doidge thinks a jury would have never believed Bishop's alibi, but a series of judges worried Bishop, who is mildly retarded, is too mentally disabled to help with his defense.
